[0001] This invention relates to the field of anchor cage installation and construction technology, specifically to an auxiliary installation device for anchor cages in wind turbine foundations and its construction method. Background Technology

[0002] During the installation of the anchor cage for the wind turbine foundation, a crane is needed to lift the upper anchor plate of the anchor cage to a certain height. Then, leveling anchors are evenly and symmetrically inserted into the inner and outer bolt holes of the upper anchor plate. After the leveling anchors are inserted, the crane slowly lifts the upper anchor plate and positioning anchors and moves them directly above the lower anchor plate of the anchor cage for installation.

[0003] During the installation of the anchor cage, when the upper anchor plate is lifted and aligned with the lower anchor plate by large hoisting equipment, the hoisting equipment needs to move the upper anchor plate slowly and steadily. During the adjustment, there may be slight delays due to crane operation, operator coordination, etc. Especially when the wind speed is high, the hoisting speed will be slower and the time will be longer. Summary of the Invention

[0008] Furthermore, the linkage mechanism includes: a transmission gear, coaxially connected to the upper end of the support column; a second driven gear; threaded holes are provided on the top seat and the base, the threaded hole of the base communicates with the accommodating cavity; the lifting member has an external thread, the lifting member is screwed into the threaded hole, the lower end of the lifting member is coaxially connected to the second driven gear; the second driven gear on the base meshes with the first driven gear; the second driven gear on the top seat meshes with the transmission gear; the thickness of the second driven gear is less than the thickness of the first driven gear and the second driven gear; when the lifting member rises and falls, the teeth of the second driven gear slide along the length direction of the groove of the first driven gear or the second driven gear.

[0009] Furthermore, a drive shaft is rotatably mounted on the base of the motor, one end of the drive shaft is coaxially connected to the drive gear, and the output end of the motor is coaxially connected to the other end of the drive shaft.

[0010] Furthermore, the upper part of the upper positioning rod and the lower positioning rod are frustum-shaped.

[0011] Furthermore, the support column is a multi-stage electric actuator.

[0012] Furthermore, the number of support units is four, and the four support units are arranged at equal intervals along the circumferential direction.

Detailed Implementation

[0026] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0027] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0028] Referring to Figures 1 to 5, the present invention provides an auxiliary installation device for anchor cages of wind turbine foundations, comprising: multiple support units A.

[0029] Multiple support units A are arranged at intervals along the circumferential direction. In this embodiment, the multiple support units A are arranged along the circumferential direction of the lower anchor plate 6 or the upper anchor plate 7.

[0030] The lower anchor plate 6 or the upper anchor plate 7 is circular. Multiple bolt holes are provided on the lower anchor plate 6 or the upper anchor plate 7. These bolt holes are evenly spaced along the circumference of the lower anchor plate 6 or the upper anchor plate 7.

[0031] Support unit A includes: base 1, support column 2, lifting component 3, and linkage mechanism.

[0032] In this embodiment, the base 1 is elongated. The base is arranged radially along the lower anchor plate 6 or the upper anchor plate 7. The base 1 has a first proximal end and a first distal end for the lower anchor plate 6 of the anchor cage to rest on. A lower positioning rod 11 is vertically provided on the first proximal end. The lower positioning rod 11 is movably inserted into the bolt hole of the lower anchor plate 6. A support 12 is rotatably mounted on the first distal end.

[0033] The support column 2 is coaxially arranged with the foundation 12. The height of the support column 2 is adjustable. The support column 2 is erected vertically on the foundation 12. A top seat 21 is rotatably mounted on the support column 2. The top seat 21 has a second proximal end and a second distal end for resting the upper anchor plate 7 of the anchor cage. One end of the second proximal end is vertically provided with an upper positioning rod 22 that is movably inserted into the screw hole of the upper anchor plate 7.

[0034] The first and second proximal ends are each equipped with a lifting component 3 that can be raised and lowered. The lifting component 3 is supported by the lower anchor plate 6 or the upper anchor plate 7.

[0035] The linkage mechanism is installed on the base 1. The linkage mechanism is used to synchronously drive the two lifting components 3 on a support unit A to rise and fall.

[0036] Referring to Figure 1, the lower anchor plate 6 rests on the first proximal end of the base of the multiple support units, and the lower positioning rod is inserted into the bolt hole of the lower anchor plate. The upper anchor plate 7 is coaxially arranged with the lower anchor plate, and rests on the second proximal end of the top seat of the multiple support units, and the upper positioning rod is inserted into the bolt hole of the upper anchor plate. Since the top seat and the base are arranged in the same direction, the lower anchor plate 6 and the upper anchor plate 7 are arranged parallel to each other. The top seat is located directly above the base. The top seat is also arranged along the radial direction of the lower anchor plate 6 or the upper anchor plate 7.

[0037] When adjusting the levelness of the lower anchor plate 6 or the upper anchor plate 7, the levelness of the lower anchor plate 6 is checked (e.g., using a level instrument 61 to check the levelness of the lower anchor plate) to determine the lower side of the lower anchor plate (i.e., the side that needs to be lifted). After driving the lower side of the lower anchor plate, the lifting component is synchronously driven to lift the lower anchor plate 6 and the upper anchor plate 7 through the linkage mechanism on the support unit near the lower side, so that the lower anchor plate 6 and the upper anchor plate 7 are set in the horizontal direction.

[0038] In this embodiment, a drive mechanism 5 is installed on the base 1. The drive mechanism 5 drives the support platform 12. The drive mechanism drives the support platform to rotate, thereby causing the support column to rotate. The linkage structure synchronously drives the two lifting components to rise and fall. Specifically, the linkage mechanism includes: a motor 51, a first driven gear 52, and a driving gear 53.

[0039] The motor 51 is mounted on the base 1. The base 1 has an internal cavity 10. The main shaft is coaxially connected to the support 12. The upper part of the base 1 has a shaft hole communicating with the cavity 10. The main shaft is rotatably inserted through the shaft hole. The first driven gear 52 is disposed in the cavity 10 and coaxially connected to the main shaft.

[0040] The drive gear 53 is rotatably mounted within the accommodating cavity 10 and meshes with the first driven gear 52. The motor 51 is driven by the drive gear 53.

[0041] In a preferred embodiment, the linkage mechanism includes: a transmission gear 41 and a second driven gear 42.

[0042] The transmission gear 41 is coaxially connected to the upper end of the support column 2. The top seat 21 and the base 1 have threaded holes. The threaded hole of the base 1 communicates with the accommodating cavity 10. The lifting member 3 has external threads. The lifting member 3 is screwed into the threaded hole. The lower end of the lifting member 3 is coaxially connected to the second driven gear 42. The second driven gear 42 on the base 1 meshes with the first driven gear 52. The second driven gear 42 on the top seat 21 meshes with the transmission gear 41. The thickness of the second driven gear 42 is less than the thickness of the first driven gear 52 and the second driven gear 42.

[0043] When the lifting member 3 is raised or lowered, the teeth of the second driven gear 42 slide along the length of the groove of the first driven gear 52 or the second driven gear 42.

[0044] In this embodiment, the motor 51 is located outside the base 1. Referring to Figure 5, the accommodating cavity is structurally designed to allow the second driven gear to rotate and move vertically within the accommodating space. A drive shaft 54 ​​is rotatably mounted on the base 1. One end of the drive shaft 54 ​​is coaxially connected to the driving gear 53. The output end of the motor 51 is coaxially connected to the other end of the drive shaft 54.

[0045] In a preferred embodiment, the upper part of the upper positioning rod 22 and the lower positioning rod 11 are frustum-shaped. When hoisting the upper and lower anchor plates, the frustum-shaped upper and lower positioning rods can quickly insert the lower positioning rod into the bolt hole of the lower anchor plate and the upper positioning rod into the bolt hole of the upper anchor plate.

[0046] In this embodiment, the support column 2 is a multi-stage electric push rod.

[0047] In a preferred embodiment, the number of support units A is four. The four support units A are arranged at equal intervals along the circumferential direction.

[0048] The present invention provides a construction method for an auxiliary installation device for anchor cages of wind turbine foundations, comprising the following steps: S1, setting multiple support units A at intervals along the circumferential direction.

[0049] S2. Hoist the lower anchor plate 6 and place it on the first proximal end of the base 1 of the multiple support units A, so that the lower positioning rod 11 is movably inserted into the screw hole of the lower anchor plate 6.

[0050] S3. Hoist the upper anchor plate 7 and place it on the second proximal end of the top seat 21 of the multiple support units A, so that the upper positioning rod 22 is movably inserted into the screw hole of the upper anchor plate 7.

[0051] S4. Check the levelness of the upper anchor plate 7 or the lower anchor plate 6.

[0052] Specifically, referring to Figure 1, a level 61 is installed on the lower anchor plate. In this embodiment, two radial rods are installed on the lower anchor plate. The two radial rods are arranged along the radial direction of the lower anchor plate. The level is located at the intersection of the two radial rods.

[0053] S5. Based on the levelness of the upper anchor plate 7 or the lower anchor plate 6, the two lifting members 3 on the support unit A on the lower side of the upper anchor plate 7 or the lower anchor plate 6 are synchronously driven to rise by the linkage mechanism to synchronously lift the upper anchor plate 7 or the lower anchor plate 6, so that the upper anchor plate 7 and the lower anchor plate 6 are set in the horizontal direction.

[0054] After determining the lower side of the anchor plate, the motor is started, and the motor drives the drive gear to rotate via the main shaft. The drive gear drives the first driven gear to rotate. The first driven gear rotates together with the support column, and then drives the second driven gear on the top seat to rotate via the transmission gear. After the second driven gear on the top seat rotates, the lifting member on the top seat rotates and rises using threads to support the upper anchor plate. On the other hand, the second driven gear on the base, driven by the first driven gear, also synchronously drives the lifting member on the base to support the lower anchor plate. With the continued drive of the motor, the lower sides of the upper and lower anchor plates are raised, so that the upper and lower anchor plates are set in a horizontal direction.

[0055] The auxiliary installation device and construction method for the anchor cage of the wind turbine foundation of the present invention, through multiple support units arranged along the circumferential direction, in conjunction with a liftable jacking component and a linkage mechanism, can quickly and accurately adjust the level of the upper and lower anchor plates after they are hoisted into place, which significantly improves the installation efficiency and accuracy of the anchor cage.

[0056] The anchor cage auxiliary installation device for wind turbine foundations of the present invention supports the upper and lower anchor plates simultaneously through multiple support units and uses a linkage mechanism to synchronously drive the lifting component for lifting and adjustment. This avoids the repeated fine-tuning operations that rely on large hoisting equipment in traditional methods, greatly shortens the installation time, and its advantages are more obvious under adverse conditions such as high wind speed.

[0057] The auxiliary installation device for the anchor cage of the wind turbine foundation of the present invention uses a level to detect the levelness of the anchor plate in real time, and combined with a precisely controllable lifting component and linkage mechanism, it can achieve fine adjustment of the levelness of the upper and lower anchor plates, ensuring the verticality and stability of the anchor cage installation and improving the overall construction quality of the wind turbine foundation.

[0058] The anchor cage auxiliary installation device for wind turbine foundations of the present invention does not require the use of large hoisting equipment for fine adjustments throughout the process, which reduces construction costs and dependence on large machinery, while also reducing installation errors and safety risks caused by improper crane operation or personnel coordination.

[0059] The support column height of the auxiliary installation device for the anchor cage of the wind turbine foundation of the present invention is adjustable and the top seat is rotatable, which can adapt to the installation requirements of anchor cages of different specifications and sizes, and has good versatility and flexibility.

[0060] The upper and lower positioning rods of the auxiliary installation device for the anchor cage of the wind turbine foundation of this invention are designed in the shape of a frustum, which facilitates quick insertion into the bolt holes of the anchor plate and simplifies the hoisting and alignment process. The linkage mechanism is driven by a motor, which is simple to operate, precise to control, reduces manual intervention, and improves construction safety.

[0061] The auxiliary installation device for anchor cages of wind turbine foundations of the present invention has a reasonable structure and is easy to operate. It can effectively solve the problems of low efficiency and long time consumption in the existing anchor cage installation process, and has strong practical value and promotion prospects.
